National engine number

[Jrtm]

Anyone know where it should be?

[billh]

On the National that I am familiar with: number is on the flywheel rim, also on the back of the engine and on the air inlet manifold. But, they are 3 different numbers, so it's anyone's guess which engine it actually is! I think you will find this is the situation with lots of old engines.

Mmm bit anoying trying to find out what boat the national fitted to towy was from

[paddles up]

On the timing cover, just behind the injector pumps. Five digits stamped into the casting.

I have recently set up the injector pump on a JP2 with a three cylinder flywheel. Old engines like to conceal their identities and set a few traps for the unwary

Fulbourne, registered in July 1937, was originally fitted with National engine number 46656. So yours is 335 engines earlier and may well have come from one of the earlier batches of GU boats.

[Jrtm]

Intresting its quite an early engine then

Wonder if pete would know

[paddles up]

I have a list somewhere, I'll dig it out.

[Jrtm]

Sweet thanks

My 3 pot national has its original works plate intact ,on the block opposite the fly wheel and just above where the timing arrow is that points to the fly wheel.

[Jrtm]

I havent seen the number i got the info from the towy group. Just need to find its original boat name now. Just be nice to know.

As far as I'm aware the engine number 46321 was originally fitted into the Corolla.

As far as I'm aware the engine number 46321 was originally fitted into the Corolla.

That is what an undated, untitled Document of unknown provenance says, but it is very possibly correct and is the Document some of my records are based upon.

[archie57]

Engine probably arrived at the Towy via Barry Lycett and John Stephenson

[Jrtm]

Was fitted between 66 and 78 engine was already in at time of towy group buying it in 78. But thanks ill have to check the number but thats what i was told

[Jrtm]

If im correct the dm2 was taken out in 1960 so must have been fitted to another boat or was in storage for a good few years before going into towy

Are you thinking COROLLA kept its original National until 1960, or are you saying you know it came out of another boat in 1960 - and what are you basing this on ?

 

Incidentally a National is a 2DM, a Russell Newbery being a DM2

[Jrtm]

If it was still in corolla it must have been sat somewhere for 4-10+ years or it was fitted to a diffrent boat and was removed from this and then it put into towy.

I know engines got swapped in and out quite a few had this done but at the same time alot of engines were kept or ended up back in there original boat.

It would seam odd to me it was still fitted to corolla as i cant really see someone removing an engine including the engine rods to have it sat or stoored till it was refitted to another boat.

So i would assume it was fitted to another boat. Either that or it was saved from scrap from bw doing an engine change.

But unless i can find the person that did it ill never know but its nice knowing what boat it was from originally.

 

Yes they are 2dms rather than dm2.

[Jrtm]

Sorry forgot to say baced it on that corolla had a national removed in the 60s but think was early 60s and a ha2 (sure was ha2) fitted.

[archie57]

HA3 was fitted for use as a Zoo Bus

[Jrtm]

Yes knew was zoo bus. Must have miss read as 2 rather than 3. Tar for correction

[Jrtm]

I know is an old thread but can anyone tell me which engine 46624 came from? I have a few bits with this engine number stamped on

[Jrtm]

I also have some bits from 71147

[Rose Narrowboats]

46624 was originally fitted to big woolwich "Aber".

 

 

Almost all the GU Nationals started in the 46xxx series (a few were 45xxx), so no idea where 71147 came from.
